Comment 4 for bug 500526

You get the same silent rejection if the ISO simply lacks /.disk/info , e.g. a Fedora 15 ISO or ReactOS ISO, see bug 705353 (which perhaps should be made a dupe of this).

To add to Mr. Greening's analysis, as I commented in bug 705353, there seems to be a logic error in 10.10's usbcreator/backends/udisks/backend.py . It doesn't test if the output of `isoinfo -J -i /path/to/Some.iso -x /.disk/info` is an empty string , so it doesn't realize it's failed, so its logging error 'Could not extract .disk/info.' is never reached! That code has a "# TODO evand 2009-07-26: Error dialog.", but maybe base/backend.py should trigger the error dialog.
